Consider the four stations SI, S2, S3, and S4 that want to send data through the same channel using the CDMA (Code Di,isiou Multiple Access) techniques used in 3G Technology. Data bits to be Sent by the four stations are (bIb2b3b4)2 respectively Now find the followings: 1.Generate, valid chips code sequences for all Station 2.Resultant channel sequence 3.Retrive Original data bits sent by all stations

Here, (b1b2b3b4)2=(4)16
